Polo Ralph Lauren 's Fair Isle sweater may be patterned from collar to hem, but the deep shades of blue keep it from feeling busy. It's jacquard-knitted from a linen and cotton-blend that's thick yet breathable. The slim shape is just roomy enough to layer over a collared shirt or under a gilet. Shown here with Officine Generale trousers, Mr P. jacket, Converse sneakers. - - Tonal-blue linen and cotton-blend - Crew neck, ribbed trims - 65% linen, 35% cotton - Machine wash
